Research on Comprehensive Decision-Making of Distribution Automation Equipment Testing Results Based on Entropy Weight Method Combined with Grey Correlation Analysis

The traditional evaluation process of distribution automation equipment relies on the judgment of experts. In order to solve the problem of insufficient objectivity of the comprehensive evaluation process, a comprehensive decision-making method of distribution automation equipment testing results based on entropy weight method combined with grey correlation analysis is proposed. Firstly, the test and evaluation index system considering eight big indexes and thirty-five small indexes is established. Secondly, the entropy weight method is used to determine the objective weight, which can avoid subjective influence and make the weighting process more objective. Then, the improved grey correlation analysis method is used to achieve the sorting of the test results of distribution automation equipment. Finally, the effectiveness of the proposed method is verified by the analysis and comparison of case studies.
